If your YouTube playlist stream is a sequence of source videos, add a persistent logo with FFmpeg’s overlay video filter. Give FFmpeg the video as its main input and a transparent logo image as a second input, then composite them before encoding the output.
Here, “playlist stream” means videos played one after another, not an HLS media playlist. HLS is a possible output protocol with its own YouTube ingestion requirements; it is separate from choosing and sequencing the source videos.
What “playlist stream” means here
A source-video playlist is an ordered set of files that your playback or encoding workflow presents as a continuous programme. For example, a devotional channel might sequence several bhajan videos, while a study channel might rotate recorded lessons. The composition step adds the logo to the video frames; it does not decide which source plays next.
An HLS media playlist is different: it describes the segments of an encoded live output for a compatible receiver. In a YouTube HLS workflow, the playlist orders output segments sent to YouTube. It is not the same thing as a text list of input videos. Keep those jobs distinct: select and sequence source material, composite the logo, encode the result, then send it using a protocol configured for YouTube Live.
That distinction matters when troubleshooting. If the logo is missing, inspect the video filter graph and its inputs. If YouTube does not accept the output, inspect the selected ingestion protocol and its requirements. A working overlay does not make an otherwise incompatible output valid for YouTube.
If you are building a channel from a rotation of videos, the guide to running a YouTube radio stream with multiple lofi playlists can help clarify the programming side. The present guide focuses on the image composition applied to whatever video frames your workflow produces.
Prepare a transparent logo image
Use a PNG with transparency for the logo layer. The transparent area lets the underlying video remain visible wherever the logo image has no opaque pixels. FFmpeg’s filter documentation uses a transparent PNG as its example overlay asset: FFmpeg Filters Documentation.
Before adding it to the command, inspect the image against a few representative frames from your programme. A logo that is legible over a pale wall may disappear against a bright sky; one that works over dark footage may dominate a lighter scene. If the channel contains both, consider whether the artwork itself needs a subtle outline or a more robust colour treatment. These are design decisions, not properties that FFmpeg can infer for you.
Keep the image’s canvas close to the logo’s actual artwork. Transparent padding around an image is still part of its dimensions, so it affects where the filter positions the image. If the visible mark is only in the middle of a much larger transparent canvas, the measured corner inset will not match the apparent inset. Crop unnecessary transparent margins or account for them while testing placement.
Also decide how large the mark should appear relative to the video. A pixel size that seems restrained on one frame may look much larger when the source has lower resolution. Test the composition at the actual output dimensions rather than judging it only in an image viewer. If you are preparing other on-screen elements, such as captions, the considerations in open versus closed captions on a live stream are useful because a logo and text can compete for the same screen space.
Add the logo as a second FFmpeg input
The essential input arrangement is simple: the source video is input zero, and the logo image is input one. A basic command shape is:
ffmpeg -i input.mp4 -i logo.png -filter_complex "overlay=10:main_h-overlay_h-10" output.mp4
This shows the filter composition, not a complete command for every playlist, codec, audio layout, or YouTube ingestion protocol. The first -i supplies the main video. The second -i supplies the image to be composited. -filter_complex connects them through the overlay filter, and the output filename stands in for the encoded result you will configure for your workflow.
An image input may behave differently from a video input with respect to frame availability and duration. For a still logo, the intention is that it be available for the frames being processed. Test the exact command and FFmpeg build you will use rather than assuming that a short local test proves the entire playlist workflow. The source sequencing, audio handling and output mapping still need to be specified for your use case.
When a command has several inputs or outputs, explicit labels make the graph easier to read and map. FFmpeg’s filter documentation shows the general pattern of feeding [0:v] and [1:v] into overlay, labelling the result, then mapping the labelled video stream to the output. The simple example above is a starting point for understanding the positions, not a universal finished playlist command.
Combine the video and logo with overlay
The overlay filter composites the second video stream over the main video stream. In this use, the main stream is your programme and the overlay stream is the transparent logo. FFmpeg evaluates the position expressions against the dimensions of those streams, so you can describe placement relative to the frame rather than relying on a fixed coordinate for every resolution.
In overlay=10:main_h-overlay_h-10, the first expression places the logo ten pixels from the left edge. The second places it ten pixels above the bottom edge. main_h is the main video’s height and overlay_h is the overlay image’s height. The documented example is useful for seeing the mechanics, but it is only a starting point: your own logo size, safe margins, aspect ratio, background and other graphics determine whether that composition suits your channel.
For a lower-right position with the same inset, use:
overlay=main_w-overlay_w-10:main_h-overlay_h-10
Here main_w is the width of the main video and overlay_w the width of the logo layer. Subtracting the overlay width and the margin places its far edge inside the right boundary. The height expression does the equivalent at the bottom. This relative placement adapts as the main frame changes size, provided the overlay itself is the intended size for that output.
The filter is not a brand-design tool. It will place the pixels you give it; it will not choose a sensible scale, ensure contrast, avoid captions, or keep the image clear of important action. Treat the graph as the mechanical composition stage, and review the visual result as a viewer would see it.
Choose and test logo placement
Corner choice is a balance between consistency and obstruction. A lower corner may avoid a presenter’s face in one video, but cover subtitles or a graphic in another. An upper corner may work for landscape footage while colliding with a title card in a different source. Review several clips from the sequence, including the frames where information or faces matter most.
| Placement choice | Coordinate pattern | What to check |
|---|---|---|
| Lower-left | 10:main_h-overlay_h-10 |
Whether captions, names or important detail sit near the lower edge |
| Lower-right | main_w-overlay_w-10:main_h-overlay_h-10 |
Whether controls, labels or subject matter make that corner busy |
| Upper-left | 10:10 |
Whether titles or framing leave enough clear space |
| Upper-right | main_w-overlay_w-10:10 |
Whether a title, watermark or key visual detail is already there |
The ten-pixel inset in these examples comes from the documented filter example, not from a universal design rule. A different frame size or a larger logo may call for different margins. Choose an inset that looks intentional at the output resolution and remains clear of the visible edge on the devices your audience uses.
Test at least one representative frame from each kind of content in the sequence. For a channel rotating lessons and devotional videos, that might mean checking a title slide, a close-up, a bright outdoor shot and a dark scene. Look for two things: whether the mark remains recognisable and whether it obscures anything viewers need to follow. If you change the logo dimensions, retest the corner expressions because the visible mark will occupy a different area.
Apply the composition to playlist output
The logo filter belongs after the workflow has selected the video frames to encode and before those frames are sent as output. If the source videos are joined or played sequentially, ensure every frame that reaches the filter graph passes through the same composition. The overlay should persist through transitions and across changes in source clip, unless you deliberately build a more complex graph that changes or removes it.
Do not assume that a command for one input file is automatically a complete playlist system. Sequencing, gaps between files, resolution differences, audio continuity, codec settings and output mapping are separate decisions. If clips have different dimensions, establish what frame dimensions the output should use and test each transition. A logo positioned relative to the main frame may remain at the corner, but changes in the underlying picture can still alter its contrast and visual impact.
If you use a playlist file or another source-selection mechanism, confirm how that mechanism exposes its video stream to the filter graph. Keep the overlay graph connected to the final video stream that is actually mapped to output; otherwise FFmpeg may process a stream that is not the one being broadcast. Explicit stream labels can help when there are multiple inputs or outputs. The official FFmpeg filter guide is the right place to check syntax as your graph grows, and its examples should not be mistaken for a full recipe for every source and muxer combination.
Only after the composition stage should you make the YouTube transport decision. YouTube offers continuous RTMP ingestion and HLS ingestion, with different configuration and latency characteristics. YouTube Help describes HLS as higher latency because it sends video in segments rather than as a continuous RTMP stream, and gives protocol and media requirements on its HLS setup page. Pick the protocol that suits your content and encoder workflow, then follow the current official guidance rather than assuming a filter command determines ingestion compatibility.
If your requirement is to keep a prepared file on air without leaving a local computer running, StreamNeo removes the need to leave the FFmpeg workstation running after you upload the video and supply your YouTube stream key; it does not add a logo for you, so prepare the composited file first. That distinction is useful if local power or an unattended laptop is part of the problem. For a local setup, the practical trade-offs are covered in streaming recorded lessons around the clock from a Windows mini PC.
Verify the result before YouTube Live
Make a local output test before connecting to a live broadcast. Check that the logo appears in the intended position from the opening frame through the end of the test, that transparency is preserved, and that the image is not unexpectedly scaled or clipped. Also watch a point where the source changes, because a graph can be correct for one file while a later source has different dimensions or framing.
Listen as well as look. The overlay filter concerns video composition, but the output must still carry the intended audio. Check that audio from the source sequence is mapped, remains present at transitions, and is in a format supported by your selected YouTube protocol. The presence of a visible logo says nothing about the audio path or the acceptance of the encoded stream.
If choosing YouTube HLS, use the creator-facing setup instructions and confirm the current requirements before you send output. YouTube Help specifies details including segment duration, outstanding segments, transport behaviour and supported media for HLS. Google’s encoder-oriented HLS ingestion guide gives additional details for implementations, including how media playlists and segments are delivered. These are ingestion requirements, not settings established by the overlay example.
FFmpeg’s HLS muxer documentation explains the muxer and its playlist and segment options. Generating an HLS output with FFmpeg does not, by itself, prove that the output meets YouTube’s current ingestion rules. Treat the filter composition and the protocol output as separate stages, and test with the exact command, media and configuration intended for the channel.

FAQ
Does “playlist stream” mean an HLS playlist?
Not in this guide. It means a sequence of source videos played one after another. An HLS media playlist describes the output segments delivered through HLS ingestion, which is a separate part of the workflow.
Does YouTube add the logo to my stream?
No. The logo is composited into the video by the FFmpeg filter graph before output is sent to YouTube. The example uses a transparent image as a second input; YouTube ingestion is a separate step.
Will the same placement work at every resolution?
Expressions based on main_w, main_h, overlay_w and overlay_h position the mark relative to the frame boundaries. That helps preserve a corner inset when dimensions change, but it does not choose the logo’s scale or guarantee that it avoids captions and important picture details. Test the actual output and source clips.
Is the overlay command a complete YouTube Live command?
No. It demonstrates the filter composition and placement only. You still need to decide how to sequence the source videos, handle audio and map streams, encode the output, and configure a YouTube-supported ingestion protocol. Check the current official requirements for the protocol you select.
